CIS/2 to VRML Translator (Online version) |
The CIMSteel Integration Standards (CIS/2) is the product model and electronic data exchange format (file format) for structural steel project information. CIS/2 is intended to create a seamless and integrated flow of information among all parties of the steel supply chain involved in the construction of steel framed structures. It has been adopted by the American Institute of Steel Construction as their interoperability format for data exchange.
From this web page, a CIS/2 file can be translated into a 3D interactive model in the form of a VRML (Virtual Reality Modeling Language) file that can be viewed in a web browser with a VRML plugin. Use the VRML plugin detector to check if your web browser is properly configured to be able to view VRML files.
The translator recognizes CIS/2 entities related to analysis, detailed (manufacturing), and design models, however, some entities related to those types of models are ignored. Users can visualize CIS/2 files and make them available on the web and software developers can verify their CIS/2 export capabilities.
The translator is based on CIS/2, IFC, and VRML research at NIST.

UsageIf you do not have your own CIS/2 files to translate, a zip file of sample CIS/2 files can be downloaded to your computer. Unzipping this file will create a directory Sample_CIS2_Files. The CIS/2 files in that directory have a file extension of .stp.
VRML InformationA VRML plugin must be installed in the web browser in order to be able to view a CIS/2 file that is translated to a VRML file. Use the VRML plugin detector to check if your web browser is properly configured to be able to view VRML files.
ValidationAlthough the translator might create a VRML model that looks correct, it does not imply that the CIS/2 file conforms to the CIS/2 structural frame schema. Conformance to the schema can be checked with tools such as Express Engine, Express Data Manager, STEP Tools, and others. A VRML model that looks correct also does not imply that the CIS/2 file follows recommended practices, software implementers agreements, or that it can be imported into another CIS/2 importing application.

The translator and web page scripts are written in Tcl (8.4.7). The online user interface uses cgi.tcl (1.10.0).
